We present a case of a 26-year-old female patient with bloating, postprandial nausea and recurrent vomiting after solid food intake. A gastric emptying scintigraphy showed a delayed gastric emptying, defining gastroparesis. Because of her past medical history of short stature and pulmonary stenosis, we initiated genetic counseling where the diagnosis of Noonan syndrome was made. Dietary therapy and medication with domperidone quickly led to relief of the discomfort due to gastroparesis. However, prokinetics are not indicated for long-term therapy, as cardiac arrhythmia may occur...

: Many variables can influence the results of the gastric emptying scintigraphy (GES). A lack of methodologic standardization may cause variability, limit comparisons, and decrease the credibility of the test. To address this, in 2009, the SNMMI published Procedure Guideline for Adult Solid-Meal Gastric-Emptying Study 3.0 which describes a standardized, validated GES protocol. Laboratories must closely follow the consensus protocol to provide valid and standardized results and improve patient care...

Introduction Gastroparesis (a complication of both type 1 and type 2 diabetes mellitus) is delayed gastric emptying in the absence of a mechanical obstruction. Overall prevalence of Gastroparesis is close to 5 % in type 1 diabetes and 1 % in type 2 diabetes. It is unclear if good glycemic control leads to delay of development and progression of gastroparesis. Methods Gastric enteric neurons as well as interstitial cells of Cajal (ICC) are depleted, truncated and are surrounded by immune infiltrates composed of macrophages...

Gastrointestinal disorders are common complications of diabetes mellitus and include gastroparesis, nonalcoholic fatty liver disease, gastroesophageal reflux disease, and chronic diarrhea. Symptoms of gastroparesis include early satiety, postprandial fullness, nausea, vomiting of undigested food, bloating, and abdominal pain. Gastroparesis is diagnosed based on clinical symptoms and a delay in gastric emptying in the absence of mechanical obstruction. Gastric emptying scintigraphy is the preferred diagnostic test...

BACKGROUND: Animal studies have increasingly highlighted the role of macrophages in the development of delayed gastric emptying. However, their role in the pathophysiology of human gastroparesis is unclear. Our aim was to determine changes in macrophages and other cell types in the gastric antrum muscularis propria of patients with diabetic and idiopathic gastroparesis. METHODS: Full thickness gastric antrum biopsies were obtained from patients enrolled in the Gastroparesis Clinical Research Consortium (11 diabetic, 6 idiopathic) and 5 controls...

INTRODUCTION: Gastrointestinal dysfunction is often described in patients with Parkinson disease (PD), and gastrointestinal symptoms are usually attributed to gastroparesis. The consequent delayed gastric emptying (GE) may be an important pharmacokinetic mechanism underlying some of the response fluctuations that develop after long-term levodopa (L-dopa) therapy.The aim of this prospective study was to assess GE time by a liquid meal scintigraphy, in PD patients, and to correlate them with demographic, clinical, and therapeutic data...

BACKGROUND: Gastric emptying scintigraphy has become the gold standard, by excellence, in gastric emptying studies. This method must be standardized for the correct interpretation of results. The ideal protocol must be performed with an egg sandwich or egg white poder, both labeled with 99mTc sulphur colloid. The aim of this study was to standardize and determine the protocol with99m Tc sulphur colloid incorporated in egg white and compare it with a hamburger labeled with 99mTc sulphur colloid as well...

PURPOSE: Gastroparesis is a frequent gastrointestinal complication after lung transplantation. Although gastric emptying scintigraphy (GES) is the standard technique to evaluate gastroparesis, magnetic resonance imaging (MRI) can also assess gastric motility and emptying. This study compared the results obtained by these two modalities. METHODS: Twenty-two lung transplant recipients underwent MRI and GES after ingesting a small pancake as a test meal. Parameters assessed on MRI included antral peristaltic wave velocity and frequency, and the ratios of gastric content volume at 15 and 35 min...

REVIEW
Harvey A Ziessman
The diagnostic imaging evaluation of patients with suspected esophagogastrointestinal transit disorders is changing. Anatomical methods, e.g., barium studies, endoscopy, manometry, radiopaque markers, have long been the techniques available and used for diagnosis. The one exception has been gastric emptying, where radionuclide scintigraphy has been the standard for decades. Esophageal transit scintigraphy is an old and reliable methodology but probably underutilized. The diagnostic use of small and large intestinal transit scintigraphy is increasing, in part, because of the limitations of the other methods but, most importantly, because it is truly physiologic, i...

Background/Aims: After exclusion of structural diseases, chronic constipation may be associated with normal or slow transit or rectal evacuation disorders. We evaluated: (1) clinical features and anorectal function, (2) difference of regional colonic transit according to the presence or absence of evacuation disorders, and (3) association of colonic transit with gender in patients with objectively slow colonic transit. Methods: We reviewed electronic medical records of 1553 patients with constipation seen by one gastroenterologist from 1994-2015 at a tertiary medical center...

BACKGROUND AND AIMS: Upper gastrointestinal symptoms are more prevalent among type 2 diabetes mellitus (T2DM) patients. The prevalence of delayed gastric emptying (GE) and factors predictive of it have not been studied in Indian T2DM patients and the present study aimed to study the same. METHODS: This hospital-based cross-sectional study involved adult (age between 18 and 65 years) outpatients with T2DM of ≥5-year duration. Measurements of GE of a labelled standardized solid rice idli meal by gastric emptying scintigraphy (GES), symptoms of delayed GE (by standardized questionnaire) and autonomic function by cardiovascular autonomic function tests (AFTs) were carried out...

In the field of gastroenterology, breath tests (BTs) are used intermittently as diagnostic tools that allow indirect, non-invasive and relatively less cumbersome evaluation of several disorders by simply quantifying the appearance in exhaled breath of a metabolite of a specific substrate administered. The aim of this review is to have an insight into the principles, methods of analysis and performance parameters of various hydrogen, methane and carbon BTs which are available for diagnosing gastrointestinal disorders such as Helicobacter pylori infection, small intestinal bacterial overgrowth, and carbohydrate malabsorption...

BACKGROUND: Gastrointestinal complications in diabetes may affect glucose and endocrine homeostasis. Glucose-dependent insulinotropic peptide (GIP), glucagon-like peptide-1 (GLP-1), and leptin regulate glucose homeostasis, food intake, and gastric emptying. AIM: The aim was to investigate associations between diabetes complications and glucose homeostasis and plasma levels of GIP, GLP-1, and leptin. METHODS: Sixteen diabetes patients (seven men) were examined with gastric emptying scintigraphy and 72-h continuous subcutaneous glucose monitoring, 14 with the deep-breathing test, and 12 with esophageal manometry...
